Geranium plant named ‘Boom Chocolatta’

ABSTRACT

The new and distinct hybrid of Hardy  Geranium  plant named  Geranium  ‘Boom Chocolatta’ with large, rounded, deeply-cleft, palmately-lobed foliage having dark bronze color. Numerous, densely-branched, erect, stems display blue-purple flowers above the foliage beginning early summer for about three weeks. The new plant is vigorous and produces large, upright, winter-hardy mounds.

Botanical denomination: Geranium hybrid.

Variety denomination: ‘Boom Chocolatta’.

STATEMENT REGARDING PRIOR DISCLOSURES UNDER 37 CFR 1.77(B)(6)

The first public disclosure of the claimed plant, in the form of a photograph and brief description on a website operated by Walters Gardens, Inc. on Feb. 1, 2018. The claimed plant was first sold on Aug. 20, 2018 by Walters Gardens, Inc., who obtained the plant and all information relating thereto, from the inventor. No plants of Geranium ‘Boom Chocolatta’ have been sold in this country or anywhere in the world, nor has any disclosure of the new plant been made, more than one year prior to the filing date of this application, and such sale or disclosure within one year was either derived directly or indirectly from the inventor.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hardy Geranium in the Geraniaceae family and given the cultivar name of ‘Boom Chocolatta’. Geranium ‘Boom Chocolatta’ was hybridized by the inventor on Jun. 7, 2012 at a wholesale perennial nursery in Zeeland, Mich., USA. The seed or female parent was Geranium pratense ‘Midnight Blues’ U.S. Plant Pat. No. 22,455 and the pollen or male parent was presumed to be Geranium clarkei ‘Kashmir Blue’. Seeds resulting from this cross were sown Aug. 9, 2012 at the same nursery.

Geranium ‘Boom Chocolatta’ was first selected in the summer of 2014 and assigned the breeder code 12-47-3 through the final evaluation process in the summer of 2016 when it was selected from among many other seedlings from the same cross and hundreds of other crosses. Geranium ‘Boom Chocolatta’ has been asexually propagated by shoot tip cuttings at the same nursery in Zeeland, Mich. in fall of 2014 initially by division and later shoot-tip, tissue culture propagation, and the resultant plants have remained stable and continued to exhibit the same characteristics as the original plant for multiple generations.

BRIEF SUMMARY OF THE INVENTION

The nearest comparison varieties include: the seed cultivar ‘Midnight Reiter’ (not patented) and ‘Dark Reiter’ (not patented). ‘Midnight Reiter’ seedlings are less robust, slower growing and has darker foliage than the new plant. ‘Dark Reiter’ is slower growing, smaller in habit and has darker foliage. ‘Midnight Blues’ is smaller in habit and leaf, less vigorous than the new plant and has darker grey-purple foliage and flowers of a different hue.

Geranium ‘Boom Chocolatta’ differs from its parents as well as all other Hardy Geranium known to the applicant in the following combined traits:

-   -   1. The large foliage is rounded, dark-bronze, deeply-cleft,         palmately-lobed;     -   2. Winter-hardy, perennial, upright mounded habit.     -   3. Flowers have medium blue-purple petals with reddish-purple         veins;     -   4. Growth is vigorous and refined.

BRIEF DESCRIPTION OF THE DRAWINGS

The photographs of the new plant demonstrate the overall appearance of the plant including the unique traits. The plants in the drawing are two-year-old plants growing in a full-sun research garden in Zeeland, Mich. The colors are as accurate as reasonably possible with color reproductions. Some slight variation of color may occur as a result of lighting quality, intensity, wavelength, and direction or reflection.

DETAILED BOTANICAL DESCRIPTION

The following description is based on a two-year-old plant growing in a partially shaded greenhouse and full-sun trial garden in Zeeland, Mich., USA. The new plant has not been grown under all possible environments and may phenotypically appear different under different conditions such as light, temperatures, fertilizer, and water, without any difference in genotype. The color descriptions used are from the 2015 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used.
